Maximum Sustained Winds
The maximum sustained wind associated with a tropical cyclone is a common indicator of the intensity of the storm. Within a mature tropical cyclone, it is found within the eyewall at a distance defined as the radius of maximum wind, or RMW. Unlike gusts, the value of these winds are determined via their sampling and averaging the sampled results over a period of time. Wind measuring has been standardized globally to reflect the winds at above the Earth's surface, and the maximum sustained wind represents the highest average wind over either a one-minute (US) or ten-minute time span (see the definition, below), anywhere within the tropical cyclone. Surface winds are highly variable due to friction between the atmosphere and the Earth's surface, as well as near hills and mountains over land. Over the ocean, satellite imagery determines the value of the maximum sustained winds within a tropical cyclone. Land, ship, aircraft reconnaissance observations, and radar imagery ca ...

1975 Pacific Typhoon Season
The 1975 Pacific typhoon season was one of the deadliest tropical cyclone seasons on record, with nearly 229,000 fatalities occurring during the season. It had no official bounds; it ran year-round in 1975, but most tropical cyclones tend to form in the northwestern Pacific Ocean between June and December. These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean. Tropical Storms formed in the entire west pacific basin were assigned a name by the Joint Typhoon Warning Center. Tropical depressions in this basin have the "W" suffix added to their number. Tropical depressions that enter or form in the Philippine area of responsibility are assigned a name by the Philippine Atmospheric, Geophysical and Astronomical Services Administration or PAGASA. This can often result in the same storm having two names. Some of the notable storms here are Typhoon Nina, which caused the Banqiao Dam flood, which resulted in approxim ...

1974 Pacific Typhoon Season
The 1974 Pacific typhoon season was the first season on record to not feature a Category 5 equivalent super typhoon; a feat later repeated by the 1977 and 2017 seasons. Even so, the season was overly active, with 32 tropical storms and 16 typhoons being developed this year. It has no official bounds; it ran year-round in 1974, but most tropical cyclones tend to form in the northwestern Pacific Ocean between June and December. These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean. The scope of this article is limited to the Pacific Ocean, north of the equator and west of the international date line. Storms that form east of the date line and north of the equator are called hurricanes; see 1974 Pacific hurricane season. Tropical Storms formed in the entire west pacific basin were assigned a name by the Joint Typhoon Warning Center. Tropical depressions in this basin have the "W" suffix added to their number. T ...

1975 Pacific Hurricane Season
The 1975 Pacific hurricane season officially started May 15, 1975, in the eastern Pacific, and June 1, 1975, in the central Pacific, and lasted until November 30, 1975. These dates conventionally delimit the period of each year when most tropical cyclones form in the northeast Pacific Ocean. The 1975 Pacific hurricane season was slightly above average, with 17 tropical storms forming. Of these, 9 became hurricanes, and 4 became major hurricanes by reaching Category 3 or higher on the Saffir-Simpson Hurricane Scale. The only notable storms are Hurricane Olivia, which killed 30 people, caused $30 million (1975 USD) in damage, and left thousands homeless when it made landfall in October; and an unnamed hurricane that developed at very high latitude, but had no effect on land. Hurricane Denise was the strongest storm of the year. Hurricanes Lily and Katrina passed close to Socorro Island and Tropical Storm Eleanor made landfall in Mexico. Hurricane Agatha sank a ship. __TOC__ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1974 Pacific Hurricane Season
The 1974 Pacific hurricane season featured one of the most active periods of tropical cyclones on record with five storms existing simultaneously. The season officially started May 15 in the eastern Pacific, and June 1 in the central Pacific, and lasted until November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the northeast Pacific Ocean. With 17 named storms and 11 hurricanes, this season was slightly above average. An additional tropical storm formed in the Central Pacific as well. The year also featured a period where six systems, Ione, Olive, Kirsten, Lorraine, Joyce, and Maggie, were all active at once on August 26, a very unusual occurrence. At the time, Olive was a Central Pacific storm that had weakened to a tropical depression while the other five were of at least tropical storm intensity simultaneously and remained so until early on August 27. Five storms were also active between t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1975 Atlantic Hurricane Season
The 1975 Atlantic hurricane season featured the first tropical storm to be upgraded to a hurricane based solely on satellite imagery – Hurricane Doris. The season officially began on June 1 and lasted until November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin. The season was near average, with nine tropical storms forming, of which six became hurricanes. Three of those six became major hurricanes, which are Category 3 or higher on the Saffir–Simpson scale. The first system, Tropical Depression One, developed on June 24. Tropical Storm Amy in July caused minor beach erosion and coastal flooding from North Carolina to New Jersey, and killed one person when a ship capsized offshore North Carolina. Hurricane Blanche brought strong winds to portions of Atlantic Canada, leaving about $6.2 million (1975 USD) in damage. Hurricane Caroline brought high tides and flooding to northea ...

1974 Atlantic Hurricane Season
The 1974 Atlantic hurricane season featured Hurricane Fifi, the deadliest Atlantic tropical cyclone since the 1900 Galveston hurricane. The season officially began on June 1 and lasted until November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin. The first system, a tropical depression, developed over the Bay of Campeche on June 22 and dissipated by June 26. The season had near average activity, with eleven total storms forming, of which four became hurricanes. Two of those four became major hurricanes, which are Category 3 or higher on the Saffir–Simpson scale. The most intense storm of the season was Hurricane Carmen, which struck the Yucatán Peninsula at Category 4 intensity and Louisiana at Category 3 intensity. Carmen caused about $162 million in damage, mostly in Louisiana, and 12 deaths. Also highly notable was Hurricane Fifi, which dropped torrential rain in Central Am ...

Plaine Des Cafres
The Plaine des Cafres is a plateau on Réunion Island, one of the French volcanic islands in the Mascarene Archipelago in the southwestern Indian Ocean. It is part of the commune of Le Tampon. It is named after the Cafres, black slaves who hid in the area during and before the 18th century. « Entre ces plaines ..la plus remarquable, et dont personne n’a rien écrit, est celle qu’on a nommée la plaine des Cafres, à cause qu’une troupe de Cafres, esclaves des habitants de l’île, s’y étaient allés cacher, après avoir quitté leurs maîtres. ..Cette plaine était inconnue avant la fuite des Cafres » (‘The most remarkable among the plains – one which nobody has written about – is one named the ''Plaine des Cafres'', for the group of Cafres (slaves of the islanders) who escaped there in hiding, after leaving their masters. ..This plain was unknown before the Cafres escaped o dwell there’) Geography Located between the two mountain ranges of Piton des ...

Cold Front
A cold front is the leading edge of a cooler mass of air at ground level that replaces a warmer mass of air and lies within a pronounced surface trough of low pressure. It often forms behind an extratropical cyclone (to the west in the Northern Hemisphere, to the east in the Southern), at the leading edge of its cold air advection pattern—known as the cyclone's dry "conveyor belt" flow. Temperature differences across the boundary can exceed from one side to the other. When enough moisture is present, rain can occur along the boundary. If there is significant instability along the boundary, a narrow line of thunderstorms can form along the frontal zone. If instability is weak, a broad shield of rain can move in behind the front, and evaporative cooling of the rain can increase the temperature difference across the front. Cold fronts are stronger in the fall and spring transition seasons and are weakest during the summer. Development of cold fronts A cold front occurs when ...

Tropical Cyclone Basins
Traditionally, areas of tropical cyclone formation are divided into seven basins. These include the north Atlantic Ocean, the eastern and western parts of the northern Pacific Ocean, the southwestern Pacific, the southwestern and southeastern Indian Oceans, and the northern Indian Ocean (Arabian Sea and Bay of Bengal). The western Pacific is the most active and the north Indian the least active. An average of 86 tropical cyclones of tropical storm intensity form annually worldwide, with 47 reaching hurricane/typhoon strength, and 20 becoming intense tropical cyclones, super typhoons, or major hurricanes (at least of Category 3 intensity). __TOC__ Overview Northern Hemisphere North Atlantic Ocean This region includes the North Atlantic Ocean, the Caribbean Sea, and the Gulf of Mexico. Tropical cyclone formation here varies widely from year to year, ranging from one to over twenty-five per year. Most Atlantic tropical storms and hurricanes form between June 1 and Novem ...
